Hire the Best Engineering Designers in San Antonio, TX

Hello and welcome to my profile! I’m a mechanical engineering student specializing in CAD design, FEA simulations, and prototype development. I help clients turn ideas into clear 3D models, engineering drawings, and 3D-printable parts using SolidWorks and ANSYS. Recently I’ve designed and prototyped a circular-correction mechanism for industrial aerospace rings, studied vibration and thermal behaviour of an automotive brake disc, and created several functional assemblies and housings ready for fabrication. Here’s what I can help you with: * 3D modeling of parts and assemblies from sketches, photos, or ideas * Manufacturing-ready drawings with dimensions and basic GD&T * STL/STEP files for 3D printing and CNC machining * Basic FEA (static, modal, and simple thermal) to validate designs * Fast communication, clear documentation, and revisions until you’re satisfied If you need a reliable, detail-oriented CAD designer for student, hobby, or entry-level industry projects, I’d be glad to work with you.

13 years of experience in all aspects of RF design and high-speed PCB development, including antennas, RF front-end circuits, RFID systems, BLE/Wi-Fi/LoRa products, RF components, impedance matching, filters, amplifiers, RF switches, baluns, and antenna tuning. Much of my work has involved RF PCB design, wireless product development, and high-speed digital hardware. This background also extends to RFID readers, transponder-based systems, and FPGA-related hardware projects. I have strong experience in RF and antenna simulation using tools such as HFSS, CST Studio Suite, and Ansys tools for antenna design, RF matching, radiation pattern analysis, impedance optimization, RF front-end validation, and wireless performance improvement. I have strong experience in high-speed PCB design, including multilayer board layout, controlled impedance routing, differential pairs, signal integrity, power integrity, EMI/ESD protection, RF grounding, shielding, and manufacturability. I have worked on FPGA-related projects involving Xilinx, Zynq, Artix-7 FPGA platforms, including data acquisition, signal processing, timing-sensitive interfaces, and high-speed digital board design. My embedded hardware experience includes the setup, integration, and debugging of microcontrollers and embedded platforms such as STM32, ESP32, ESP32-S3, Nordic nRF52832/nRF52840, Raspberry Pi, Arduino, and embedded Linux-based systems. I am familiar with RF and wireless ICs/modules including Semtech SX12 series LoRa devices, Nordic BLE chips, ESP32 wireless modules, Quectel LTE/GPS modules, u-blox GPS modules, RFID reader modules, RF filters, LNAs, PAs, RF switches, baluns, and matching networks. For PCB design, I use Altium Designer, KiCad, EasyEDA, Eagle, and OrCAD I also have experience with enclosure design for RF and embedded products, including plastic and metal enclosures, antenna placement, RF keepout areas, mechanical fit checks, connector positioning, thermal considerations, waterproofing concepts, mounting features, and PCB-to-enclosure integration. I understand that enclosure design can directly affect RF performance, antenna efficiency, heat dissipation, usability, and manufacturability, so I always consider the mechanical structure together with the electronics. I have worked for years on IoT devices, wireless sensors, RFID products, antenna-integrated PCB designs, FPGA boards, digital electronics, embedded controllers, data acquisition systems, and prototype-to-production hardware. System engineering and integration have been important parts of many of my projects, especially where RF, firmware, FPGA, PCB design, and enclosure design must work together reliably. My main strength is not only designing a schematic or PCB, but building complete hardware that works reliably in the real world. I always consider RF performance, signal integrity, grounding, shielding, power stability, EMI/ESD protection, enclosure integration, manufacturability, testing, and long-term reliability from the beginning of the design.
